U.S. plane manufacturer Boeing, which had initially complained that Bombardier was benefitting
from unfair subsidies by the Canadian
government, had only asked for an 80 % levy.
At issue is the assertion by the Big Three U.S. airlines — Delta, American and United — that the Gulf carriers have received $ 42 billion in
subsidies from their
governments since 2004, violating open skies agreements by giving them an
unfair advantage in the international aviation market.
